They are useful for researchers working in all aspects of science and technology where fluorescently labeled cells and/or tissues are required. The molecular structure of CellVue® dyes consist of long aliphatic hydrocarbon tails linked to a polar fluorescent chromophore. These extremely lipophilic fluorescent dyes rapidly and stably integrate into the phospholipid membrane of cells or other membrane-containing bioparticles by non-covalent interactions.

The dyes are stably maintained within the lipid bilayer through strong hydrophobic interactions and do not transfer into the unstained membranes of adjacent cells. This characteristic permits a labeled cell to be tracked for extended periods of time. The rapid incorporation of the dye also allows for immediate analysis of cell functions without any waiting period. The pattern of fluorescence staining within the membrane may vary depending on the cell type. All of the dyes are designed to be biocompatible at optimized concentrations.
